You know, I've seen some studies, albeit from sources that have an interest in the outcome, that demonstrate that various veggies are much more nutritious in so-called "organic" form.
Unfortunately, I'm not convinced that the controls are solid, and I have a problem with their scaling of results. In other words, are the veggies they comparing apples to apples (literally) and do the difference in nutritional value make a nutritionally significant difference.
What good is an organic vegetable with XXX% better Vitamin whatever content than the commercial one, as long as the commercial one has sufficient nutritional content?
I am conducting my own nutritional anecdotal study for the last 3 years, focussing on fitness and eating almost exclusively commercial veggies. So far, at 45, I'm in terrific shape. I can tell the difference in days when I eat enough veggies, throughout the day, but I can see no signs that I'm deficient in any nutrition.
And I'm too cheap to pay the extra for so called "natural" foods.
